CLEVIS.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed December 28, 1917. Serial No. 209,289.

To all whom it may concern:

Be it known that I, JOHN ZUKIWSKI, a subject of the King of England,residing at Isspas, in the Province of Alberta, and Dominion of Canada,have invented certain new and useful Improvements in Clevises, of whichthe following is a specification.

This invention relates to clevises and has special reference to clevisessuch as are used for farm implements, chains and the like.

One important object of the invention is to improve the generalconstruction of devices of this description.

A second important object of the invention is to provide an improvedform of clevis adapted to fit varying thicknesses of equalizers ordoubletrees.

lVith the above and other objects in view, as will be hereinafterapparent the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

Figure 1 is a side elevation of a clevis constructed in accordance withthis invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a detail perspective view of the toggle end of the togglebolt.

In the embodiment of the invention herein illustrated there is shown inthe drawings a clevis which constitutes a J-shaped body 10 and there isprovided an eye 11 at the end of the longer limb 12 of this body, theaxis of this eye intersecting a prolongation of the axis of the shorterlimb 13. A post 14: extends from the extremity of the shorter limbparallel to the axis of the eye 11 and in a direction away from the limb12, the post being threaded, as at 15, at its extremity. In order tomake the two limbs of equal length there is provided a link 16 having aneye 17 at each end. One of these eyes is threaded and engages on saidpost. Now by means of this construction the link bar 17 may be moved byrotation on the threaded post from or toward the longer limb 12 inaccordance with the equalizer or other bar which the clevis is adaptedto fit. Through the remaining eye 17 and the eye 11 passes a bolt 20which is used to connect the clevis to the equalizer or other member andat one end of this bolt 20 is pivoted a toggle 21 arranged with beveledfaces to aline with the bolt 20 as shown in Fig. 3. Surrounding the bolt20 is a compression spring 22 which is positioned between the eye 11 andthe head 23 of the bolt so that the toggle, when in the position shownin Fig. 1 is prevented from working loose. It will be obvious that thisclevis is applied in the usual manner to the swingletree or otherelement and the bolt passed through the eyes 11 and 17 and the toggleturned down. The spring 22 will serve to hold the parts in position.

There has thus been provided a simple and efhcient device of the kinddescribed and for the purpose specified.

t is obvious that many minor changes may be made in the form andconstruction of the invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described but it is wished to includeall such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new is l. Aclevis comprising a J-shaped body member having an eye at the end of itslonger limb, the axis of the eye intersecting the axis of the shorterlimb prolonged, a post extending from the extremity of the shorter limbparallel to the axis of said eye and in a direction away from the longerlimb, the said post being threaded, a link bar having an eye at eachend, one of said eyes being screwed on said post, and a bolt passingthrough the remaining eye of the link bar and the first-menti ned eye.
